ATHENS

246 KM

SPARTA

The body at its limit.
Identity laid bare.

Kilómetros infinitos is the account of a double journey: that of a runner taking on the Spartathlon —246 kilometres between Athens and Sparta— and that of a man who discovers he is autistic at forty-nine.

For months, David Lladó prepares every detail to endure more than thirty hours without sleep, cross the Peloponnese heat and climb Mount Parthenion at night. But no strategy can prevent certainty from falling apart when the body begins to fail.

Far from a sports manual or a conventional tale of overcoming, the book brings adventure and autobiography together to explore identity, vulnerability and difference. Running is not an escape, but a way of listening to the body and understanding a mind that has always worked differently.

WHY READ KILÓMETROS INFINITOS

01

To experience an impossible race from within

The Spartathlon is not a backdrop: readers move with the runner through scorching roads, time checkpoints, sleepless nights and moments when one more step seems absurd.

02

To understand adult autism beyond clichés

A late diagnosis reorganises an entire life. The book shows difficulties and strengths honestly, without presenting autism as either a sentence or a superpower.

03

To recognise yourself, even if you have never run

Perfectionism, anxiety, a need for control and a desire to belong: the book’s real distance is the gap between who we are and who we think we should be.

I discovered ultrarunning had something that suited me: structure, repetition, hyperfocus, inner control.

Portrait of David Lladó

David
Lladó

Technologist, cultural manager and ultrarunner. Diagnosed as autistic at forty-nine, he has found in ultrarunning a space for personal exploration and understanding.

Kilómetros infinitos is his first book.

You do not need to run. You do not need to be neurodivergent.

Kilómetros infinitos can be read as the story of an extreme race, the search for an explanation that arrives late, or a story about finding your own way of being in the world.

Do you need to run to enjoy Kilómetros infinitos?

No. The Spartathlon gives the book momentum and tension, but you do not need to know anything about racing to enter the story. Ultrarunning is a place where distractions disappear: when the body reaches its limit, the important questions remain—who you are, what you need, and what brought you there.

Do you need to be neurodivergent to feel addressed by it?

No. The book tells a personal story of an autism diagnosis in adulthood, without claiming to represent every experience or provide universal answers. Yet it speaks to something many people recognise: years spent trying to fit in, not fully understanding certain difficulties, and searching for fairer language to explain oneself.

Is it a book about sport or identity?

It is both, and that is precisely its singularity. Preparing for an extreme race, exhaustion, the route and the finish line coexist with an intimate journey: discovering an identity that went unnamed for years. It is neither a training manual nor a guide to autism; it is an autobiographical account of moving forward and understanding yourself.

What might someone looking for their own place find here?

A story that offers neither formulas nor perfect endings. David Lladó follows a very specific path—through the Spartathlon and a late diagnosis—to explore accepting difference, revisiting guilt and finding spaces in which to live with more calm and authenticity. Knowing yourself better does not solve everything, but it changes where you look from.
